v0.94.480

A battery above its Max SoC with terminal-value tiers set no longer loses the whole plan; two flex-signal fixes.

• A battery's plan-consistent headroom never exceeds its physical headroom
  (#1985). For a battery
  already charging or discharging flat out, the flex signals'
  available_up_ranging_kw / available_down_ranging_kw could report room it
  did not have, read from the solver's ranging of the limit itself. They are now
  clamped to the physical figure. Dispatch is unchanged.

• A battery above its Max SoC no longer loses the whole plan when terminal-value
  tiers are set (#1987).
  A live reading over Max SoC that could not discharge back under it by the tier
  period made every solve infeasible, so nothing was planned for any battery or
  load. The tier row now takes the excess off, as it already did below Min SoC
  (#328). Plans that end within Max SoC are unchanged.

• A load's shut period always reads as degenerate
  (#1981). A period
  outside an adequacy load's window has a zero band, but its degenerate flag in
  the flex signals' load_signals followed the solver's unclamped ranging, so
  another load in the same solve could turn it off. It now follows the band.
  Dispatch is unchanged.

• Devhub validation: confirmed live on devhub (HA 2026.10.2) at d74c74c
  (release/0.94.480), installed via HACS and restarted at 08:06 AEST. The new
  code is the one running: devhub's own log reports the departure-target warning
  from solver/network.py line 5213 (5192 in 0.94.479; #1987's tier change moved
  it). Its 08:15 solve came back optimal in every phase, and the Forecaster
  sensors refreshed by 08:20. No new Nimbus ERROR or traceback against the
  pre-install log; the rest is devhub's known baseline.

  • Not exercised on devhub: a battery above Max SoC with terminal-value
    tiers (#1987). devhub's battery is not over Max SoC; the tests in #1988 carry it.

• Consumer check: nothing changes for a plan that stays within Max SoC. An install
  with terminal-value tiers set and a battery reading above Max SoC now gets a plan
  instead of none. On the Flex tab, a battery charging or discharging flat out no
  longer shows ranged headroom it does not have, and a load's shut periods always
  read as degenerate.
